' I 'natingl' devices .and more particularly to a combination pressuregage and tire milater 'if desired.

; "Anotliei'objeotof the invention is to pro- ;vide a novel fornirciconnection between the pressure gage and iniiaiier whereby the sup- Ifthe object beingto-provide a'sirnple'and efficient combination deviceby means ofwhich;

the` tirev pressure canbe quickly andveasily gaged orindicated, andadditionally inflated ply connection can be checked while the tireVpressure is being" gaged, and automatically openedwhen additionalpressure or inflation of the tire is desired.v A

l'Another vobject of the'invention fis to provide a simple` andefficient tire vvalve connec tion fortheinflatingdevice. f i

With these .various `objects in view our invention consistsessentially,v in combining a pressure gage with'efoloseJ` connection and'tire valve connection,'j's'a1d `p ,age being Inovable to cut off thenhose connection rfor the` purpose of gagging tirepressure.

kThe invention consists also in certainnovel `features'of constructlon'and combination of parts hereinafter fiillyescribed and pointed out in'thegclaims. c
